JUVE Comment

This leading firm in patents is one of the standout patent litigation firms thanks to numerous opposition and nullity suits conducted primarily by patent attorneys like Ehlers and Göken. The patent attorneys are also very experienced litigating in infringement proceedings (e.g. for Enercon, Philips and Nordson), and traditionally active globally, with one example the ground-breaking arbitration work for Enercon in India. In a number of high-profile proceedings, e.g. Sisvel, the patent attorneys worked with external litigators, but also increasingly litigate with ES’ own lawyers. The preeminent prosecution practice made steady progress in terms of work, but had the loss of a Munich partner to Prüfer & Partner to cope with.
